slackware resolution problems


I need a higher resolution. I've searched around here a little and tried some of the solutions by editing /etc/X11/xorg.conf and none have worked. Here is the "screen" part of that file:

Code:
# **********************************************************************
# Screen sections
# **********************************************************************

# Any number of screen sections may be present.  Each describes
# the configuration of a single screen.  A single specific screen section
# may be specified from the X server command line with the "-screen"
# option.
Section "Screen"
    Identifier  "Screen 1"
    Device      "VESA Framebuffer"
    Monitor     "My Monitor"

# If your card can handle it, a higher default color depth (like 24 or 32)
# is highly recommended.

#   DefaultDepth 8
#   DefaultDepth 16
   DefaultDepth 24
#   DefaultDepth 32

# "1024x768" is also a conservative usable default resolution.  If you
# have a better monitor, feel free to try resolutions such as
# "1152x864", "1280x1024", "1600x1200", and "1800x1400" (or whatever your
# card/monitor can produce)

    Subsection "Display"
        Depth      24
        Modes "1280x1024"
    EndSubsection
    Subsection "Display"
        Depth      24
        Modes "1280x1024"
    EndSubsection
    Subsection "Display"
        Depth      24
        Modes "1280x1024"
    EndSubsection
    Subsection "Display"
        Depth      24
        Modes "1280x1024"
    EndSubsection

EndSection
Despite this edit, the 1280x1024 resolution I desire doesn't show up in GNOME's screen resolution tool.

I'm using a NEC AccuSync 90* monitor and a GeForce4 MX 420 video card. (And Slackware 10.1)

Thanks.

* Apparently I cannot post the URL for the monitor information, so here it is.

Resolutions Supported:
640 x 480 @ 60 to 160 Hz
800 x 600 @ 55 to 153 Hz
832 x 624 @ 55 to 144 Hz
1024 x 768 @ 55 to 120 Hz
1152 x 870 @ 55 to 105 Hz
1280 x 1024 @ 55 to 89 Hz
1600 x 1200 @ 55 to 76 Hz

Synchronization Range (Automatic):
Horizontal: 31 kHz to 96 kHz
Vertical: 55 Hz to 160 Hz

not sure why you have 4 subsections for the same display, maybe first try
removing 3 of them, and what does the resolution start up as if its not
accepting that 1280x1024?
and do you have the proper HorizSync and VertRefresh for your
specific monitor in the Monitor section?

Yes, why do you have four subsections.
Code:
Subsection "Display"
        Depth      24
        Modes "1280x1024"
    EndSubsection
    Subsection "Display"
        Depth      24
        Modes "1280x1024"
    EndSubsection
    Subsection "Display"
        Depth      24
        Modes "1280x1024"
    EndSubsection
    Subsection "Display"
        Depth      24
        Modes "1280x1024"
    EndSubsection
Either take out three of them and leave the one you want or comment the lines out like:
Code:
Subsection "Display"
        Depth      24
        Modes "1280x1024"
    EndSubsection
#    Subsection "Display"
#        Depth      24
#      Modes "1280x1024"
#    EndSubsection
#    Subsection "Display"
#        Depth      24
#        Modes "1280x1024"
#    EndSubsection
#    Subsection "Display"
#        Depth      24
#        Modes "1280x1024"
#    EndSubsection
-=-EDIT-=-
And if that does not work, try lowering the resolution a bit more such as 1024x768.

Okay, I changed my xorg.conf file by taking out the extra subsections and changing HorizSync and VertRefresh to reflect my monitor's ability..still nothing happened (it continues to use 1024x768 and I still only get options for 1024x768, 800x600, and 640x480 in the GNOME screen resolution utility.) However, my refresh rate did increase to 85 Hz.

Here it is.

Code:
# **********************************************************************
# Monitor section
# **********************************************************************

# Any number of monitor sections may be present

Section "Monitor"

    Identifier  "My Monitor"

# HorizSync is in kHz unless units are specified.
# HorizSync may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY.  REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.

    HorizSync   31.5 - 96

#    HorizSync  30-64         # multisync
#    HorizSync  31.5, 35.2    # multiple fixed sync frequencies
#    HorizSync  15-25, 30-50  # multiple ranges of sync frequencies

# VertRefresh is in Hz unless units are specified.
# VertRefresh may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY.  REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.

    VertRefresh 55-160

EndSection


# **********************************************************************
# Graphics device section
# **********************************************************************

# Any number of graphics device sections may be present

Section "Device"
    Identifier  "VESA Framebuffer"
    Driver      "vesa"
    #VideoRam    4096
    # Insert Clocks lines here if appropriate
EndSection

# **********************************************************************
# Screen sections
# **********************************************************************

# Any number of screen sections may be present.  Each describes
# the configuration of a single screen.  A single specific screen section
# may be specified from the X server command line with the "-screen"
# option.
Section "Screen"
    Identifier  "Screen 1"
    Device      "VESA Framebuffer"
    Monitor     "My Monitor"

# If your card can handle it, a higher default color depth (like 24 or 32)

#   DefaultDepth 8

#   DefaultDepth 32

# "1024x768" is also a conservative usable default resolution.  If you

    Subsection "Display"
        Depth      24
        Modes "1280x1024"
    EndSubsection

No problem. Will always try to help. I *was* going to suggest that your shared memory size may also be small and might of been needed to be largened. Anyways, good luck. =)
